Catalogue: Ground Cover
Dr Rohan Nelson, ABARE"s principal natural resources economist and co-author of the report - "Forecasting the regional impact of climate variability on Australian crop farm incomes" - hopes it will allow climate policy advisers to develop guidelines for more timely and better targeted drought assistance... Dr Nelson says that climate data that has been collected around Australia for many years is not as useful on its own as when put into the context of how rural communities cope with adverse climate conditions... Dr Nelson says that since current drought policy is focused on enhancing the self-reliance of farmers, increasing the diversity of farm income sources could be one of the most effective policy options for reducing the vulnerability of farm households to climate variability...

Based on this, we estimate that water used by weeds in the wet weedy (+I+W) treatment up to the midfallow period was 593 x 1688 (biomass) / 10 000 = 100 mm; for the dry weedy (-I+W) treatment water use is estimated at 30 mm... The results showed that Zn uptake by plants and in the grain could be most improved by mixing Zn with N and P (as technical grade MAP and ammonium nitrate dissolved in water) in a single solution and injecting it into the soil to a depth of 40 cm... Results from our laboratory experiments have confirmed that fluid forms of P have very different physical and/or chemical effects on soil in the fertilizer band in calcareous soils, and improve plant P uptake...

The program now has significantly enhanced technical capability and a new project using a commercial partner to deliver this capability nationally has commenced... WhopperCropper has sufficient capability to impact upon risk management decisions of farmers... WhopperCropper has been used to quantify and physically demonstrate (i.e. graph) the effects of inputs, which has added capability to the experience and 'gut feel' of advisers...
